VENTILATING SYSTEM.

Application filed November 3, 1922. Serial No. 598,834.

To all whom it may concern:

Be it known that I, ERNST GLANTZBERG, a citizen of the United States,and a resident of the city of New York, borough of Manhattan, in thecounty and State of New York, have invented a new and ImprovedVentilating System, of which the following is a full, clear, and exactdescription.

y invention relates to a ventilating system and aims to provide new anduseful improvements in connection with a structure of this nature and ismore particularly adapted for use in connection with large hotels,schools, etc.

It is well appreciated that a great amount of difficulty has beenexperienced in the ventilation of large buildings of the type specifiedin the preceding paragraph. This difii culty is to be predicated by thefact that it has been heretofore considered necessary to provide eitherventilating ducts communieating with each room and hall to be aired, orto utilize fans in each room and hall which would force the air tocirculate therethrough.

These expedients, to say the least, have been unsatisfactor the firstinvolving a great amount of expense incident to the installation of theducts, etc., as well as presenting in many instances an unsightlyappearance at the outlet or intake ends of these ducts. The provision ofa number of fans for ventilating purposes is also open to objections inthat the noise of these fans has been annoying aside from the fact thatthe installation in this instance also has been expensive, it beingnoted that the maintenance or a series of separate ventilating units hasrun into a prohibitive figure.

Thus my present invention aims to provide a ventilating system by meansof which an entire floor or a number of the same may be ventilated, itbeing also noted that the occupants of the floor may optionally cause acessation of air flow in any one of the rooms thereof, if this isdesired.

A further object of my invention is the provision of a system of thecharacter specified, which will eliminate the necessity of a number ofseparate installations or a series of ducts, thus avoiding expenseincident to this type of system.

Further objects of the invention will appear in the annexedspecification, taken in connection with the drawings, which lattereration, the single present one practical embodiment of the same, and inwhich,

Figure 1 is a sectional plan view of the floor of a building equippedaccording to my improved system, this view being taken substantially online 1-1 of Fig. 2;

Fig. 2 is a vertical section through the building.

It will be seen that in the embodiment illustrated I have shown myinvention as applied to a building which is U-shaped in cross section.In other words, the building includes a pair of wings 5 and 6 and a mainconnecting portion 7, each floor being provided with a main and branchcorridors 9 and 10, respectively, the latter communicating with a seriesof compartments or rooms 11 each being provided with windows 12 andtransoms 13, preferably above the doors 14, which latter communicatewith the corridors 10.

This is obviously merely one type of building to which my improvedsystem is applicable, it being noted that I have described theconventional arrangement of so corridors and rooms in a building of thistype, although obviously any other arrangement of the partitions of thebuilding might be resorted to without in the least affecting theoperation of the system.

Attention is invited to Figure 2, from which it will be seen that I haveprovided a battery of fans 15 of any desired type, one of which isprovided in this form for each two floors. Each such fan or blower isshown conventionally as driven by electric motor 17 Conduit 18 isutilized to enclose the fan. Such conduit has its upper portionconnected to an opening 16 at the inner end of the main corridor 9 of anupper floor and has its lower portion connected to an inner end of asimilar opening 16 for a lowerfloor.

In normal operation, assuming that the doors 14 are closed and thetransoms 13 opened and that one of the fans 15 is in opfan servin toventilate a plurality of floors in that the air will be drawn in throughwindows 12 and transoms 13 of each room 11, halls 10 and main corridor 9and opening 16 of one floor, and expelled in a reverse direction throughthe similar elements of the other floor; it being also noted in thisconnection (reference being had to Figure 1) that even the outer- Je i;

most ends of the halls 10 will have a certain amount of air flowingthrough them. the occupant of any room desires to control the amount ofair passing through the same this may readily be accomplished by closingthe transom 18 associated with this room, in which instance the air willbe incapable of passing into the room.

Thus my invention is adaptable to old buildings as well as to new ones,and an architect, in connection with the latter type of buildings, isenabled to provide an excessive Ventilation with a relatively small fanor blower by simply enlarging the transon'is 13 to a size insuring thisbeing accomplished although it will be seen in many instances that theoccupant of a room. may obtain an excess of ventilation by opening thedoor 14 of the chamber thus presenting an unobstructed passage for theflow or" air.

From the foregoing it will also be appreciated that l have provided aventilating system in which the necessity of a number of separate unitsfor ventilation of separate chambers or rooms is avoided, it being alsoseen that the necessity of a large installation is eliminated, thusreducing the cost to a minimum.

Furthermore, each of the rooms and halls will be eliiciently ventilatedat a minimum of expense, and thus all the objects set forth in thepreamble of this specification will have been accomplished.

Obviously numerous modifications of structure and adaptations of thesystem may readily be resorted to without in the least departing fromthe scope of my claims, in which:

1. A ventilating system including in combination with a building havingadjacent floors presenting corridors, chambers communicating with saidcorridors and windows in the outer walls of said rooms, of a fan, andmeans for connecting said fan to dififerent floors whereby to cause aito be sucked through said windows, rooms and corridors out one floor andto be expelled into the corridors, rooms and through the windows of thesecond floor with which said tan is connected.

2. A ventilating system including in combination with a house havingsimilar floors each presenting corridors, chambers in communication withsaid corridors and windows in the outer walls of said chambers, of a fanand a conduit within which said fan is positioned, said conduit havingits ends connected to different floors whereby upon said fan beingoperated air will be sucked through the windows, chambers and corridorsof one floor, through the conduit, and be expelled through thecorridors, chambers and out the windows of the other floor with whichthe opposite end of said conduit is connected.
